What does phase mean?

Answer 1

an AC power supply such as mains electricity has an alternating voltage - goes up and down (like a wave). The current used in the thing being powered often has some capacitance or inductance. Too hard to explain with text, look it up!. The current alo goes up and down but not in sinc with he voltage, so this is referered to as not in phase. f the current IS isinc with the voltage, it is IN PHASE, usually because the thing being poerede is a pure simple resistor.

Other uses for the term IN PHASE referes to any two thing that happen repeatedly at the same time.

Answer 2

A phasor or complexor (also called a sinor) is a time independent quantity which is used to describe a sinusoid completely. Phase is the measurement of this time independent quantity. It depends upon the circuit parameters and also on the type load taken into account.

Answer 3

Do you mean 'phase current'? In which case, it is the current flowing through each 'phase' of a three-phase system. Perhaps you mean 'phase angle', in which case it's the angle (expressed in electrical degrees) by which the load current leads or lags the supply voltage.

Answer 4

In general, a phase refers to a distinct stage or step in a process. In the scientific context, it can also refer to the state of matter (solid, liquid, gas) or the position of a wave in relation to a fixed point.

Answer 5

A phase is one point or portion in a recurring series of changes. The phases of the moon are New Moon, First Quarter, Full, and Last Quarter.

Answer 6

The phase at any point on a given wave is the time that has elapsed since the quantity has last passed through zero point of reference and passed positively.
